United States PatentvNo. 1,053,477 issued February-18,- 1913, to Margaret L. Heald, eXecutrix of EugeneH. Brown, for pneu? matic folding-machine, shows a foldingmachine operated by pneumatic 'pressurefor folding collars and cuffs. My present in-, vention is an improvement upon the folding machine shown and describedin said patent and consists of substantially the same mech anism and operation-shown in said patent with the exception that the a cylinder; which operates the head of the folding machine is differently. constructed, operated and located as.will behereinafter;described; and in ad'- d tiqn ,tQthemech ism showninzsa-id patent I show, a. mechanism for; piling collanrblanksieets dtetlsatee Tit; tonne On aton who.

by the foot of the operator. There are other details and new features in the machine for making the same operate more rapidly and which will appear in the specification and drawings. v

Referring to the. drawings, 1 represents the frame of the machine. 2 is the die. The goods are pressed over the die and the die is not collapsed until the oods are pressed. The die is made in two sections as shown in Figs. 6 and 7. The die may be made'of any suitable thin metal. The two sections of the die are held together by blocks 3, 3 which are so'constructed as to allow the die to be adjusted in different lengths. The die itself is made in any style and size which may be desired by the manufacturer. The "blocks 3, 3 are attached to the sections of'the die in any suitable manner.

4: is an alin'ementrod extending into the blocks3, 3 to keep the sections'of the die in properalinement in folding the. goods. The blocks 3, 3 are called fold holders and hold the fold in scribed. r c 1 V p 5, 5 are eccentrics for operating the sections of the die. The eccentrics 5, 5are'at tached to the blocks as shown in Figs. 11 and 15. V

'6, 6 aretwo levers fixedly attached to the eccentrics. These levers are connected together by a rod 7 and the rod 7 has the pin v8 which operates inthe slot 9 in-thecamblock 10 so that when the cam-block 10 moves from left 'to right it moves the rodl 7 along-with it and moves the connecting levers '6, '6 and operates the eccentrics 5, 5

one-quarter of a turn and thisfcauses the r sections of the diet') open and collapse. The

cam-block 10 is operatedby the rod 11 by means ofthe cam roll 12 which is'fiXedly attached to the rod 11. The rod 11 is attached to the U-shaped arches 13, 13 by any suitable means at corresponding ends of the arches. The arches 13, 13 are also fixedly attached at their opposite ends to the bar 14;. The bar l l rotates in bearings 15,15 and is'operatd by the crank 16 which is fixedly attached to the bar 14' and is in turn operated by the link- 160 which is operated by the piston 18. The piston 18 operates the link 160in one direction only. The link 160 is returned to place by the spring 19, as

shown in Fig. 2. The spring 191s a continuation of the rod 20 which is attached to the piston 18' by the arm 17 to which the link 160 is hinged.

21 is the bed-plate of the machine. 'Figs.

9, 1( 11 and 12 show the bed-plate with one 7 sectlon of the die only, it being understood that the corresponding section ofthe die has like blocks and operating "mechanism: The

the goods as hereinafter de-' collar blanks may be placed upon the bed plate by hand or by any suitable means as by the automatic feeding device for which I have filed in the Unitted States Patent Oflice an application for patent, dated October 4th,

1913, Serialv No. 793,351. After the goods are fed upon the bed-plate the die which is attached to the die-head 22 descends upon the goods and the folder-plates fold the edges of the collar blanks over the edges of the die and they are pressed over the die,

iwithout the die being collapsed, and then after the folder-plates are removed the'die with the goods upon it, without being'collapsed, takes the goods from the bed-plate to thepiling table 23, Figs. 5 and 21. The die piston 18,, as above described. WVhe n the piston 18 returns the rod 14 rotates in its bearlngs and in turn swings the U-shaped arches 13, 13 which operate the rod 11 which in turn carries the die-head. v 24: and '25 are guide-links to maintain the die in a horizontal position. The die-head carrying the dieproceeds until it reaches the position shown in Fig. 21. The die is thencollapsed and the goods deposited in a pile as shown in saidfigure. 26 is a plunger which rests uponthe spring 28 as shown in said figure.

29 is a guide of any suitable construction or form for holding the collars in a uniform pilejwhen deposited upon the receiving table from the die. The die .is collapsed by the rotation of the bar 11 to which is attached the cam roll 12 as shown'in Figs. 5 and 8. When the bar 11 rotates in its bearings, by

die and the arches 13, 13 asheretofore described, the

cam;roll'12 is operated and comes in contact with the trigger 30 which holds the cam 10 in position until the screw 12 has traveled below the trigger 30. The cam roll 12 then releases the cam'10 and causes the spring 31 to draw the cam 10 from left to right and also moves with it the rod 7 attached to the cam and the levers 6, 6 attached to the rod 7. The levers 6, Gbeing attached to the eccentrics cause them to turn and collapse the die asabove described. When it reaches this position the die collapses and the goods drop ff in the pile; The die-head then carries the die back in position. 7

32 is aspring mounted on the cam 10 which operates the trigger 30 after thescret v 12 has traveled'above thetrigger 3O atJWhich time the spring 32 springs the trigger back to position.

33 is an electric wire leading from the electrical apparatusv of the feeding machine to the valve on the folding machine;

34 is a like wire also leading from the feeding machine to the valve of the folding machine. When the current is applied to the wire 33 from the switch 35 which is a part of the feeding machine the magnet 36 is energized which by the force of. its magnetism operates thepiston valve 37 so as to open the port and allow the compressed air to flow from the pipe 38 into the port 39 and so into the cylinder 40. The compressed air forces the piston located in said cylinder upward. This piston in turn forces upward the connecting rod 41 attached to the piston in the cylinder which is in turn attached to the pedal rod 42 by the pivot 43. The pedal rod 42 is pivotally attached to the valve lever 44 by the pivot The valve lever as performs the same functions and is the same as valve lever i in U. S. Patent No. 1,053,477.

The die-head carrying the die is removed from the bed-plate by the reverse operation. When the wire 34 comes in contact with the switch 46 and closes said contact, as shown in Fig. 4:, the wire 33 is no longer inicontact with the switch 35. The switch 4-6 being closed the magnet 47 is energized and the valve 37 is moved the other way and closes the air chamber and opens the exhaust port and lets the air out of the cylinder 40, causing the connecting rod 41 to descend, allowing the spring l8 to draw the pedal rod 4-2 down, causing the valve lever 44 to open the exhaust port and at the same time close the pressure port. This allows the folder-plates to withdraw, as will be hereafter described, and allows the die-head carrying the folded collar blank to go back in position and deposit the blank in the pile as already described.

49, as shown in Fig. 2, is an air pipe 6X- tending from the compressed air chamber, as shown in Fig. 28, connecting the compressed air chamber with the magnetic operating mechanism just described. Otherwise the compressed air chamber and the valves and ports and the operation of the same are as described in U. S. Patent No. 1,053,477.

Constructed in this way my folding machine is adapted to be used with the automatic feeding machine for which I have applied for a patent as above stated. The feeding machine feeds automatically to the folding machine. The folding machine then takes the goods and folds and presses them over the die and the die withoutbeing collapsed takes the goods from the bed-plate of the machine and piles them on the receiving table as hereinbefore described... The feed be fed upon the bedplate of the foldingma chine when: the die-head carrying'the die-c plate is removed from the, bed-plate, as above described, and is depositing the-blank upon the receiving table and the bed-plate is free from the die-plate. The mechanism for timing this operation is described in my ap plication for the feeding machine abovereferred to. The fold-holder operating with the die, keeps the goods and thefold in better condition, and delivers the goods more accurately than can otherwise be done.

The electrically operated foot pedal works much more easily and rapidlythan by hand or foot power and the work of placing the blanks in the machine is far more rapid and accurate than can possibly be done by hand and the two machines being used together will fold collar and cuff blanks more economically and rapidly than can otherwise be accomplished.
